John Deere B Camshafts

Jeremy White · Dec 30, 2012

Hi! I'm working on my 1939 John Deere B and I am going to install a crankshaft out of a 1942 in it to put the newer style rods and all in it. Before I go any further I need to know if the Camshafts are the same in a 39 model B and a 42 model B or are they different. I'm just trying to make sure timing marks won't be an issue when I get to that point which is soon! Any help or advice is Greatly Appreciated! Thanks!

200999 and down is different than 200999 and up.This is for styled B's. Bill

Not gaining a thing swapping a worn out 73 yr old cam for an worn out 70yr old cam.
Send the 39 cam and followers to a shop for re-grinding.

Look in the parts book (free online) compare if the part # is the same.
